Hello
Im having the classic amd gpu issue and am going to install a gfx 765 alienware in it.
I was told it only runs on High Sierra and newer osx.

Since I was on El Capitan 10.11.6 I moved the kext lib to make the mac start using the integrated intel card... Well its not really a disable but good enough to get it to start osx and upgrade to high sierra from app store.

After it downloaded/ restarted and getting ready for the install it just keeps staying on the grey startup page with the apple logo... nothing happens - waited more than a hour. And I am connected to a wifi.

Now I am consedering if its because that new installer is trying to use the Real amd gpu since I dont asume the installer dmg is looking into the osx on the harddisc that I moved the amd kext extentions.

What other options do I have.... find another mac that I can install the high sierra from if I put the imac in target diskmode maybe?

Many thanx
